To all whom itmay concern:

Be it known that l, TIMOTHY F. MORRIB- SEY, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in a Cushion for Headpieces of Radio Apparatus, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: To relieve the annoyance incident to the pressure of the supporting members of telephonic receivers employed in radio receiving apparatus; to provide a cushion for said headpieces which will not harbor vermin or carry infection; to provide cushions of the character mentioned which may be readily and easily attached to and removed from the head-gear; and to provide simple means for securing the cushion in position.

Drawings:

Figure 1 is a pictorial view partially in section of a radio receiving set having installed thereon a cushion constructed and arranged in accordance with the present in vention, the apparatus being shown in conjunction with fragmentary representation of the human head.

Figure 2 is a detailed view showing the cushion with which the head-gear is provided, the cushion being partially closed and par 'tially cut away to show the method of installing it in service and the interior construction thereof.

Figure 3 is a cross section on enlarged scale of the headrest, the section being taken on the line 3-3 in Figure 1.

Figure 1 is a detailed view showing the cushion is-constructed and arranged in accordance with the modified form there-of.

Figure 5 is a cross section on enlarged scale of the modified form of the headrests, the section being taken on the line 55 in Fig. 4.

Description To avoid the inconvenience which the metal band 10 occasions when resting in direct contact with the scalp of the person using the telephonic receivers 11 and which are supported on the adjusting rods 12 in sockets 13 formed at the ends of the band 10, a cushion preferably an elongated pneumatic tube is is employed to rest between the metal band and thescalp.

As seen best in. Fig. 2 of the drawings, the

tube 14: is constructed of two light layers of rubber superposed one on the other and united at the edges 15 thereof by any suitable cement or adhesive. The guncture of the two pieces extends completely .around three sides and partially around the fourth end, which however is held open to form a tubular passage 16 into which is forced the small rigid tube 17.

The tube 17 may be a turkey bone or small piece of hollow bamboo The inner end is covered loosely by a rubber band 18. The band 18 while covering the end of the tube 17 is not'attached thereto so that air blown through the tube 17 will displace the rubber 18 where it covers the inner end of the tube 17, thus admitting air to the channel 16.

It is obvious that when the force of the pressure on the air in the tube 17 becomes less than the pressure within the tube 14;, the valve formed by the rubber strip 18 Will close, thereby imprisoning the air held in the tube 14. The material forming the channel 16 is wrapped firmly by means of a cord 19 on the tube 17.,

The neumatic tube 14: being thus constructe the double edges or margins 15 are provided, the one with female portions 20 of snap fasteners, while the opposite margin 15 has a series of male members 21 of snap fasteners, cushion may be installed in service by placing it on the headrest or band 10 beneath the lower surface of the same, while the margins 15 are overlapped at the upper side of the band for securing the edges together. In practice this is usually accomplished with the tube 14 deflated as a better adjust- Altter the tube 14 is in position, the operator by applying his lips to the tube 17 and blowing therethrough, may initiate the tube 14.

The modification shown in Fig. 4 of the drawings consists in employing the eyelets 2:2 and the lasing string 23 in lieu of the snap fasteners 20 and 21 When. thus equipped the sider as falling within the scope of the present invention and claims based thereon.

Claims: 1. The combination with a head band of a telephone head set of a pneumatic cushion member adapted tobe disposed beneath said a in conformity therewith, means for inflating said tube, edge flaps, extending from said tube, and functioning means associat ed with said edge flaps'for securing said flaps over the upper part of the head. band to retain said tube in position.

3. A cushion for telephone head sets comprising an elongated substantially elastic member adapted. to be she din conformity with the head band of t e head set, said elastic member having laterall extendin flaps along each longitudinal e ge adapte .2

for folding over the head band of the head set, and means for attaching said flaps together over said head band for retaining the cushion in position.

4. A cushion for telephone head setslcom- 3 prising an elongated pneumatic tube adapted for inflation and for disposition between thehead band of a head set and the head of a wearer, said tube having the material thereof extended at each longitudinal edge 5 in a lateral fla of a length'suflicient to fold over the head and of the head set, andfastening elements carried by said flaps for inner engagement over said head band for retaining said tube in position TIMOTHY F.
